Hi guys.

I purchased a used ecu to go in my 2019 golf gti, I matched the numbers but the ecu came from a seat Cupra.

Odis online refused to code the ecu, do you know if it is posible top flash the box code for the ecu so I can convert it to VW spec.

My original ECU ID was : 5g0906259s

New ecu ID is : 8v0906259r

anyone who can help, or do it for me will be handsomely rewarded.

Thanks
